I applied online. I interviewed at TikTok (Sydney) in Sept 2025
Interview
Went through two out of three interviews with TikTok, in both they asked basic concurrency, networking and language specific questions as I was going for a C++ role.
They also asked Leetcode Medium questions in both interviews.
Really poor organisation from the HR team, with the main online interview being performed in their car with no camera. Maybe this was an outlier from others but still hurt my experience
